Water End Swallow Holes is a biological site of Special Scientific Interest in Hertfordshire, south-east England. Located in Welham Green and under the planning authority of Welwyn Hatfield District Council, it has an area of 11.3 hectares (28 acres).[1][2]
The site covers more than fifteen swallet holes, the only ones in chalk which are a permanent feature of the landscape. Next to the holes is a swamp area of willow carr which is biologically important, and in deep water there is reed sweet-grass. The site also has areas of woodland and grassland.[1] From the sinkholes the waters become the River Colne.
There is access to the site from Station Road.
